Description

technical field [0001] The invention relates to the collection of surface electromyography signals in a prosthetic that can be worn on the skin surface, and specifically refers to a prosthetic surface electromyographic signal collection system based on a wireless sensor network. Background technique [0002] Surface electromyography (sEMG) can use electrodes attached to the surface of human muscles to collect human muscle electrical signals without damage, and characterize neuromuscular activity through temporal and spatial data sets of independent neurons. Surface electromyographic signals have been widely used in the control signals of prosthetic medical device interface technology, and have many advantages: first, compared with traditional interface technology, it has the characteristics of convenience, quickness and operability; second, surface electromyography Electrical signals are easier to acquire, have greater amplitude strength, and produce more usable signal class...
